Abstract
An Infra Red detector system and method is disclosed. There is benefit in providing signal processing functions into each pixel of a 2D focal plane IR detector for applications such as hostile target detection. The thermal characteristics of muzzle flash or a projectile and it's trajectory for example are distinguishable from background scene. A technique to add a signal detection function to normal IR detector thermal imaging operation to a standard direct inject Integrate While Read (IWR) pixel circuit and for providing target detection at extremely high data rates is described.
